The latest outputs from researchers, alumni and friends at the UCL Centre for Advanced Spatial Analysis (CASA).
I produced this data map which forms the front cover of this week’s British Medical Journal (BMJ). The graphic shows the volumes of Barclays Cycle Hire bikeshare users in London, based on journeys from February 2012 to January 2013 inclusive. The routes are the most likely routes between each pair of stations, as calculated using […]

Although the art installation on the second day of the summit would clearly fall into the ‘doing’ category, participation in the installation was mostly in the ‘contributory’ form: after summit participants handed over […]

Continue reading »The second day of the summit (see my reflections on the first day) started with an unplanned move to the Darwin Lecture Theatre of UCL. This was appropriate, as the theatre is sited in a place where Charles Darwin used to live, and he is mentioned many times as a citizen scientist. Moreover, the unplanned […]

[Buy this print!] London North/South shows every building block in central and inner city London, coloured blue if it’s north of the River Thames and red if it’s south. And that’s all. No other features are shown, and yet, from this simple premise, a map of the city appears. Almost every street is visible, as […]

From James Borrell‘s opening with his lessons from a year of citizen science, to Leo Bottrill who closed the day by discussing the Moabi platform that is being developed for forest communities in the Democratic Republic of Congo, the issue of ‘inclusiveness‘ appeared throughout the day.

[Buy this print!] A couple of years I drew a quirky tube map to commemorate the completing of the circle on London’s Overground, affectionally known as the Ginger Line. The artwork has proven to be quite popular so I’ve produced a print run of an updated version of it. The new version retains the circles, […]

Here is the clip from the programme that covers the discussion about the […]
The second version of this online course starts on 26th February. Register here. I posted a comment when the course began and that is still relevant. Click for this. There is a shortish neat manual that tells you about last … Continue reading →

A special delight during my PhD research was to discover, at the UCL library the proceedings of […]

The Guardian’s Political Science blog post by Alice Bell about the Memorandum of Understanding between the UK Natural Environment Research Council and Shell, reminded me of a nagging issue that has concerned me for a while: to what degree GIS contributed to anthropocentric climate change? and more importantly, what should GIS professionals do? I’ll say from the start […]
I’ve been modelling the interconnected nature of the global economy by simulating a reduction in demand for various sectors in various countries. It’s a very simple little piece of analysis: What would happen if the demand for a given sector in a given country was reduced by a single US dollar? In answering this question […]

The theme is citizen science for exploring and improving our urban environment. Some of … Continue reading →

Over the past few years I’ve been looking at lots of relief maps – i.e. those showing geographical topography, specifically land elevation, and I’m generally struck by two things. Firstly how the colour schemes commonly used seem too dominant, which seems to reduce the brain’s capacity for […]

Get the design wrong and you might find yourself tied up in knots, battling against the structure of the project you defined months before. Get it right and you’ll leave yourself a extensible platform to develop into, allowing yourself …

As an update to the last post, I’ve put the agent script model of the live tube trains on the web. This shows the “nearly” live positions of all tube trains in London. One warning though, you need to reload the page to refresh the data. I wasn’t planning on releasing this just yet, so …

In the early 1960s two American geography professors, John Nystuen and Michael Dacy, were working on a way to make sense of a huge database of telephone records in Washington state. Clearly the majority of calls were being made either to or from Seattle, the state’s largest city, but they suspected there was more underlying […]
